2004 Honda Accord CD Player Error

I have a 2004 Accord EX 6speed MT with Factory Navigation System. It comes with a factor 6 CD Changer and out of nowhere today the CD Player stops working. Everytime I try to play the CD, it stalls and the ERROR message comes up. I cannot eject or load any new cd's. I've been reading online that if I have to pay for this it can go up to $500+? Also, I heard that I might be able to get a Honda Dealership to fix this on good faith or something like that? Any suggestions? Thanks!
